Biosynthesis of phosphatidyl glycerophosphate in Escherichia coli.
نویسندگان
چکیده
An enzyme (L-glycerol 3-phosphate: CMP phosphatidyltransferase) catalyzing the synthesis of phosphatidyl glycerophosphate from CDP-diglyceride and L-glycerol 3-phosphate has been rendered soluble by treatment of the particulate, membrane-containing fraction of E. coli with Triton X-100 and has been partially purified. The enzyme, devoid of phosphatidyl glycerophosphatase activity, is specific for L-glycerol 3-phosphate and is completely dependent upon added Mg(++) or Mn(++) for activity. It has high affinity for CDP-diglyceride and can be used for the assay of this nucleotide. Other properties of the enzyme are also described.

Membrane-bound phosphatases in Escherichia coli: sequence of the pgpB gene and dual subcellular localization of the pgpB product.
The phosphatidyl glycerophosphate B phosphatase of Escherichia coli has a multiple substrate specificity and a peculiar dual subcellular localization in the envelope. Its phosphatidyl glycerophosphate phosphatase activity is higher in the cytoplasmic membrane, while phosphatidic acid and lysophosphatidic acid phosphatase activities are higher in the outer membrane. The DNA sequencing of the pgp...
متن کاملEffect of Concomitant Lycopene Biosynthesis on CoQ10 Accumulation in Transformed Escherichia coli Strains
CoQ10 and lycopene are isoprenoid compounds with nutraceutical and pharmaceutical benefits. In this study, the effect of concomitant lycopene biosynthesis on CoQ10 accumulation in transformed Escherichia coli DH5α was studied. A lycopene production pathway including geranylgeranyl diphosphate synthase (crtE), phytoene synthase (crtB), and phytoene desaturase (crtI) from Erwinia herbicola was co...

A previous report from this laboratory (van Golde, L.M.G., Schulman, H., and Kennedy, E.P. (1973) Proc. Natl. Acad. Sci. U.S.A. 70, 1368-1372) described the discovery in Escherichia coli of a novel class of oligosaccharides, containing glucose as the sole sugar, substituted with glycerophosphate units derived from membrane phospholipids, and with succinic acid in O-ester linkage. These membrane...

Experimental data are presented on the intracellular localization in rat liver of three enzymes which are involved in the biosynthesis of phosphatidylethanolamine and diphosphatidylglycerol. These enzymes are phosphatidylserine decarboxylase, CDP-diglyceride-l-alpha-glycerophosphate phosphatidyl transferase, and phosphatidylethanolamine-l-serine phosphatidyl transferase. It was found that the f...
متن کاملIncreased synthesis of phosphatidylserine decarboxylase in a strain of Escherichia coli bearing a hybrid plasmid. Altered association of enzyme with the membrane.
A strain of Escherichia coli bearing a hybrid plasmid containing the psd gene, starved for isoleucine by the addition of valine, produces amounts of phosphatidyl-serine decarboxylase, a membrane-bound enzyme, about 40-fold higher than wild type. At least 98% of the enzyme from cells with high levels of decarboxylase is isolated in the inner, cytoplasmic membrane fraction if the cells are broken...
